Hundreds of Russian attack drones and more than two dozen cruise missiles targeted Ukraine overnight, killing at least two people, Ukraine said.

The legislation, which would allow the president to levy a 500% tariff on imports from countries that purchase Russian uranium, gas and oil, has gained momentum in the Senate as Trump has signaled he will escalate US action against Russia.

Russia fired 597 drones and decoys, along with 26 cruise missiles, into Ukraine overnight into Saturday, Ukraine's air force said.

President Volodymyr Zelenskiy said that Russia launched 597 drones and 26 missiles, killing two people, wounding 20, and damaging civilian infrastructure from Kharkiv and Sumy in the northeast to Lviv, Lutsk, and Chernivtsi in the west.

Officials say a Russian drone barrage has targeted the center of Kharkiv, injuring nine people and damaging a maternity hospital in Ukraine’s second-largest city.

The latest assault included more drones in a single night than Russia used in the entire month of July last year.
